Hello,
Please suggest me a way to allow my users to download a file from one link on the web page and the File is located in a different folder (This is a Link to another file server).

Balu,
Which technology are you using? Assuming ASP.NET, you may StreamRead the file and the write into the Response Stream, allowing suitable buffers. You may need to have impersonation to have ASP.NET access the network resources.

vasudevan,
Thanks for your response and i appreciate it. The technology i am using is JSP->Struts->Bean. The environment is Unix. There is a seperate server for files from appserver. This is a report where the jsp is loaded with recordset results and allows user to download the same in excel form. The files that user downloads has to be stored in the fileserver aswell. There is one Link created on the appserver to a file server. The link is outside the web folders on App server. Is it possible to allow user downloads when the file resides outside web folder (link especially).
Thanks and hope to get some help from you.
Regards,
Balu

A user can not download a file outside the web folder, unless the user has direct access to the file server.
Make a proxy page, that gets the file from the file server, and sends it as response to the user.
Make sure that the page can only be used to fetch the files that the user should have acess to, otherwise you will open up a huge security hole...

Is there any web server that raises server side events. For Example, I want to show account balance to my customers via emails at the start of month based on the records stored at server side Database.
Is there any event which raises at the first of every month?

Shoaib,
There would'nt anything from the server as such other than the possibility of the following:
(*)Your ability of accessing the server console and having privileges to create and run scheduled tasks.
(*)Sql also would enable you to do this.
Is this what you are looking for?

In Classic ASP, how do two applications make use of the same Virtual
Directory?
Specifically, if a file in the Virtual Directory referenced the ASP
Application Object, how would the Server know which Application Object
to return?
Or is it the case that a Virtual Directory can only belong to one ASP application at a time?
I guess what I am asking is this -- if two distinct ASP Applications both want to use the same physical directory, would they each need a distinctly incarnated Virtual Directory to do it?

Hi... I have never used javascript before, so i think it's a bit difficult for me. But i promissed to help a friend who has created a web shop in java. With some kind of software, that has created his code. So the source is a mess.
My problem is when you have to type your customer adress, i want to open it in a new window, not in the iframe (That how it works know, i think..!)
I want customerdtl.html to open in it's own window
orderContentFrame.location="../customerdtl.html";
Hope someone can help af javascript newbie

Use the window.open method:
widow.open('../customerdtl.html', '_blank');
You can also use a thirt parameter, specifying the size of the window that is opened, and some other stuff.
Be aware that the form might rely on being opened in the iframe. You might have to change some of the code there also to make it work.

This method is used to open a new browser window
window.open('../customerdtl.html','name','height=200,width=150')
name is a string containing the name of the new window.

alerttxt = alerttxt + "must be filled out!";
alert(alerttxt);

Hi,
I have a small HTML with a button and a handler object which is likely to catch the button's onclick event. When I try to click the button it says "this.button.id is null or not an object". If I do onclick="objHelper.buttonClick" in the "input type=button" tag instead it works fine. What is the right solution?
Here is my code:
<title>
function helper()
{
var button;
this.setButton = function(tobjButton)
{
this.button = tobjButton;
this.button.onclick = this.buttonClick;
};
this.buttonClick = function()
{
alert(this.button.id);
};
}
var objHelper = new helper();
function init()
{
objHelper.setButton(document.all("btnButton"));
}
Thanks:
(K)

Hi there,
When I try to click the button it says "this.button.id is null or not an object"
At the time the buttonclick function executes, the this keyword refers to the button object, not the objHelper. And the button object certainly does not contain any button member, so the this.button is undefined, then it should raise the error when you are accessing the this.button.id.
If I do onclick="objHelper.buttonclick" in the "input type=button" tag instead it works fine
Now you invoke the function buttonclick of the objHelper object, so the this keyword in the function should refer to the objHelper, and as a result it should be working as you expected.
To work around, you can simply change a bit your sample code:
this.buttonclick = function()
{
alert(this.id);
};

Hi everyone,
I have a problem on validation the controls in the datagrid. When I entered a control and enter an invalid value, the control will fire OnBlur event after I lost the focus of the control. It show me the alert message but the focus is not set back to the control that has the invalid value.
Anyone, please help me on how to set back the focus on the control with the invalid value after the alert message is showed, so that the user will immediately know he had entered an invalid value. Below is my javascript
function vldValue(args)
{
var IsValid;
var validFormatRegExp = /^((\-)\d)?\d*(\.\d{3})?$/;
IsValid = validFormatRegExp.test(args);
alert("Invalid Value!");
return IsValid;
}
thanks a lot in advance.

Hi there,
Basically, to set the focus on an element, you can simply call the object.focus() method, so to set the focus back to the control that has an invalid value, you need to get reference to the control, then invoke the focus() method.

Hi,
I have tried to set the focus by using object.focus() method, it doesn't work on controls in datagrid. Simply, I can't found any reference of the control. It prompt an error as null.
By the way, do you know the code of using SendKeys in javascript?
Thanks a lot,
Chiari

How do you get the value of the input control to validate? IMO, if you can access the value of the control to validate, then you probably have an idea how to access the control via its id, name ..., the sample code looks something like:
...
var txtBox = document.getElementById("datagrid1_ctl1_txtUserName");
txtBox.focus();
...AFAIK, there is no method in javascript that behaves like the SendKeys method in the window-based application. However, you can catch up the events when the user presses the keys and determine which keys are pressed.
